If you are an expert in Cucumber software then this is for you. Let us know if you looking for a job change? Then do not worry, we’ve a right answer for your job interview preparation. If you are preparing for Cucumber job interview then go through Wisdomjobs interview questions and answers page. Cucumber is a software testing tool which tests other softwares. It runs automated acceptance tests written in a behavior-driven development (BDD) style. It is used along with Selenium, Watir and etc. There are certifications to improve the visibility in interview. Good knowledge on the Cucumber is must to crack the interview. Below are the Cucumber interview questions and answers which makes you comfortable to face the interviews:
Cucumber is a Behavior Driven Development (BDD) tool. Cucumber is a tool that executes plain-text functional descriptions as automated tests. The language that Cucumber understands is called Gherkin.
In BDD, users (business analysts, product owners) first write scenarios or acceptance tests that describes the behavior of the system from the customer’s perspective, for review and sign-off by the product owners before developers write their codes.
Cucumber execution will starts from support. In support first it will load the env.rb file then it will load hooks.rb and then it will start execute feature file scenario steps.
We can create Cucumber profiles to run specific features and step definitions
We can use following command to execute a cucumber profile
cucumber features -p <profile_name>
Ex: cucumber features -p regression
Before: execute before the feature file execution
After: executes after the feature file execution
BeforeStep: executes before the each step execution
AfterStep: executes after the each step execution
cucumber tags used to filter the scenarios. We can tag the scenarios and we can execute the scenarios based on tags, We can add tags to scenarios with @ We can use following command to execute a cucumber tagged scenarios.
cucumber features -t @<tag_name>
Ex: cucumber features -t @test
Cucumber dry run is used to compile cucumber feature files and stepDefinitions. If there is any compilations errors it will show when we use dry run
Ex: Cucumber features –dry-run
Scenario outline is used to execute the same scenario with different test data.
No it is not mandatory to used keywords while writing scenario steps.
We can write the scenario steps like the following without using keywords
* I am on the landed page
We can use the following command to generate html reports.
–format html –out report.html –format pretty.
We can run particular scenario from a feature file by giving the scenario line number
Ex: cucumber features/test.feature:21
To run functional tests written in a plain text Cucumber tool is used. It is written in a Ruby programming language.
Advantages of Cucumber:
The 2 files required to execute a Cucumber test scenario are
Feature file in cucumber consist of parameters or conditions required for executing code, they are:
Feature: Visit XYZ page in abc.com
Scenario : Visit abc.com
Given: I am on abc.com
When: I click on XYZ page
Then: I should see ABC page
Scenario Outline: Same scenario can be executed for multiple sets of data using scenario outline. The data is provided by a tabular structure separated by (I I).
A step definition is the actual code implementation of the feature mentioned in feature file.
For example to make visitor visit the site “wisdomjobs” the command we use for given:
Given (/^ I am on www.wisdomjobs.com$/) do
end – This will visit www.wisdomjobs.com
A test harness for cucumber and rspec allows for separating responsibility between setting up the context and interacting with the browser and cleaning up the step definition files.
Gherkin language is used to express scenario in feature files and ruby files containing unobtrusive automation for the steps in scenarios.
A regular expression is a pattern describing a certain amount of text. The most basic regular expression consists of a single literal character.
BDD or Behaviour driven development is a process of developing software based on TDD (Test Driven Development) which focusses on behavioural specification of software units.
Ruby and its Development Kit
IDE like ActiveState
Watir ( To simulate browser)
Ansicon and rspec (if required)
Features/ support file contains supporting ruby code. Files in support load before those in step_definitions, which can be useful for environment configuration.
BDD is becoming widely accepted practice in agile software development, and Cucumber-JVM is a mainstream tool used to implement this practice in Java. Cucumber-JVM is based on Cucumber framework, widely used in Ruby on Rails world as well as in Java and .Net.
Cucumber-JVM allows developers, QA, and non-technical or business participants to write features and scenarios in a plain text file using Gherkin language with minimal restrictions about grammar in a typical Given, When, and Then structure.
The feature file is then supported by a step definition file, which implements automated steps to execute the scenarios written in a feature file. Apart from testing APIs with Cucumber-JVM, we can also test UI level tests by combining Selenium WebDriver.
